SPECIFICATION forming part of Letters Patent No. 632,389, datedSeptember 5, 1899.

Application filed February 18, 1898. Serial No. 670,850. (No model.)

To all whom, it nuty concern:

Be it known that I, ALPHONSO V. WILBUR, a citizen of the United States,residing at Stockton, in the county of San Joaquin and State ofCalifornia,have invented certain new and useful Improvements in Flows;and I do hereby declare the following to be a full, clear, and exactdescription of said invention, such as will enable others skilled in theart to which it most nearly appertains to make, use, and practice thesame.

This invention relates to improvements in plows, and more particularlyto that class of plows known as gang-plows; and it consists in the novelarrangement and construction of the parts hereinafter set forth anddescribed.

Plows of the general description and style shown herein have beenprovided with a rear gage-wheel which has been provided with suitablemountings upon an inclined arm and as a rule have been caused to trackor follow after the last or innermost plow of the gang and in the furrowof that plow. Under some conditions of soil, particularly in thatcondition in which it will be turned up in clods or lumps which fallback in the path of the gagewheel, causing the same to ride over them,this produces a great strain on the frame of the plow, as well as anirregularity in the fur row, in many instances throwing the entireimplement out of line. It is to overcome this objection that the presentinvention is designed.

In the drawings, Figure 1 is a side elevation of the rear end of theplow of the class known as gang-plows, showing this invention as appliedthereto, the gage-wheel trackingin the furrow. Fig. 2 is a sideelevation of the same, showing the gage-wheel set to track upon the landinstead of in the furrow. Fig. 3 is a detail view of the mountings forthe crank-axle. Fig. 4 is a plan view of the invention as applied to theframe of a plow, showing in dotted lines the position of the gage-wheelwhen mounted so as to track on the land and in full lines the gage-wheelmounted to track in the furrow.

The gage-wheel A is mounted on an axle A, secured to the end of theinclined crank-arm A The inclined crank-arm is mounted in a straightbearing A which is bolted to the frame of the plow. The extension A onthe crank-arm is turned at an angle of ninety degrees and is purposelyconstructed of considerable length to provide for as great a lateraladjustment of the gage Wheel as possible. This lateral adjustment isattained by means of the construction shown in the drawings,particularly at Fig. 3. This adjustment relates to two featuresthe twinor split journal A A and the set-collar A". The latter is adjustablysecured, by means of a set-bolt A upon the extension A By loosening theset-bolt A the extension A may be adjusted laterally within considerablelimits in the twin boxes A A and the set-collar when so adjusted is setin position by tightening the bolt A By means of the arrangement j ustdescribed for providing the mountings of the rear gage- Wheel with meansfor lateral adjustment the said gage-wheel may be caused to track moreaccurately in the line in which it is desired to travel.

The vertical adjustment of the gage-wheel A is performed by means of thelever B, which is fulcrumed on the frame of the plow and connected tothe lower end of the crankarm by the connecting-link B and the clamp C.The clamp C is bolted securely around the lower end of the crank-arm andis pro vided with an extension C, at the outer end of which is pivotedthe wheel-scraper D. The lever B is constructed in the form of abellcrank, having a short arm 13 to increase the leverage on the longarm 13.. The short arm is connected to the link B by means of a boltpassing through perforations B in the upper end of the link B. By meansof these perforations the adjustment of the gage-wheel may be varied andpermanently set. The lever B is fulcrumed or pivotally mounted at B in adetent-quadrant B into the teeth of which the latch 13 strikes to lockthe lever in position. The latch B", with its pull-rod B and suitableconnections for operating the same, are shown by me in an accompanyingapplication executed on the 11th day of J anuary, 1898. \Vhen the groundis in such a condition as to make it undesirable that the gage-wheel Ashould track in the furrow, it

too

may be by this construction shifted so as to extend over onto the landbeside the furrow. In the drawings at Fig. 1 is shown the gagewheeltracking in the botton of the furrow 'and behind the last plow, while'inFig. 2 it around, so as to extend to the rear of the axle of thegage-wheel instead of, as previously, in front of the same. Thescraper-blade D is then reversed so as to operate in the same directionwith reference to the travel of the wheel. The other partsto wit, thelever B, the detent-frarne B and the link B'remain in the same relativeposition as when running in the furrow, though they are transferred tothehandle-beam or land-beam X of the plow. This transfer of the parts isreadily and rapidly made, as by means of the collar A. The crank-journalmay be drawn from the twin boxes and reversed. By releasing the clamp Cfrom the crank A it may 7 be thrown around and brought quickly into itsnew position to be connected to the link 13, with which it is thensecured by means of a bolt.

The raised position of the gage-wheel when on the land is provided forin the bolt-holes B thus accommodating the raising and lowering of thegage-Wheel A;

Having thus described this invention, what is claimed is 1. In a plow, aframe having a journalbearing thereon, a crank-arm, an angular extensionupon said arm jou rnaled in said bearin g and adapted to enter the samefrom either side thereof, a gage-wheel journaled upon said crank-arm,vand means for swinging the crank-arm upon its angular extension as apivot, whereby the elevation of said gagewheel is varied; substantiallyas described.

2. In a device of the nature indicated, a frame, a crank-arm journaledupon the same and adapted to be swung to extend to either the front orthe rear of the bearing, a gage- Wheel upon the arm, and a clamp uponthe arm and carrying a scraper for the wheel,whereby the clamp membercan be loosened and swung about the arm to present the scraper in properposition with relation to the wheel whether said wheel be in front orrear of the crankarin bearing; substantially as described.

In testimony whereof I have hereunto set my hand this 27th day ofJanuary, 1898.

ALPHONSO V. VVILBUR.
